use strict in JavaScript | Post Details - SKML Home Tuitions
Use strict in JavaScript
For a long time, JavaScript evolved without compatibility issues. New features were added to the language while old functionality didn’t change.
That had the benefit of never breaking existing code. But the downside was that any mistake or an imperfect decision made by JavaScript’s creators got stuck in the language forever.
This was the case until 2009 when ECMAScript 5 (ES5) appeared. It added new features to the language and modified some of the existing ones. To keep the old code working, most such modifications are off by default. You need to explicitly enable them with a special directive: "usestrict".
use strict
The directive looks like a string: "use strict" or 'use strict'. When it is located at the top of a script, the whole script works the “modern” way.
For example:
"use strict";
// this code works the modern way
Quite soon we’re going to learn functions (a way to group commands), so let’s note in advance that "use strict" can be put at the beginning of a function. Doing that enables strict mode in that function only. But usually people use it for the whole script.
Ensure that “use strict” is at the top
Please make sure that "use strict" is at the top of your scripts, otherwise strict mode may not be enabled.
Strict mode isn’t enabled here:
alert("some code");
// "use strict" below is ignored--it must be at the top
"use strict";
// strict mode is not activated
Only comments may appear above "use strict".
